Question

Quizplus · Accepted Answer

The CR for an AP supine chest should be aligned perpendicular to the long axis of the sternum, which helps to ensure proper positioning and accurate visualization of the chest structures. Aligning the CR at the level of the jugular notch or xiphoid process could lead to improper positioning and/or inadequate visualization of certain structures. Aligning the CR perpendicular to the long axis of the clavicles is not required for this projection.
